Westward #10-32 UNC Bottoming Tap

This Westward straight flute hand tap cuts internal threads to a #10-32 UNC specification. It is made from high speed steel with a bright, uncoated finish. The bottoming chamfer allows threading close to the base of a blind hole. The tool features four flutes and a right hand thread direction with an H3 thread limit.

Replaces worn or damaged #10-32 threading tools

This tap upgrades from a taper or plug style when threads must start near the bottom of a blind hole. It is not suited for through holes where a taper or plug chamfer clears chips more effectively. Buyers needing a different thread size, pitch, or thread limit should select the matching specification.

Questions about this item

What size tap wrench fits the #10-32 tap?

Use a tap wrench sized for #10 thread taps; the square shank on this 2 3/8 in overall length tool fits standard #10 wrench jaws.

How do you start the bottoming tap without cross-threading?

Drill the correct tap drill hole, apply cutting fluid, align the tap squarely, and turn slowly; the short 7/8 in thread length and bottoming chamfer need careful alignment to start cleanly.
